Example of movement with new pathfinding

nickelpro / mcvarint.py

Created November 5, 2013 02:20

Two python functions that implement the new Minecraft varint type (32-bit signed integers packed into Google protobuf varints). Packs varints into a byte string, unpacks varints from a buffer that has a read(bytes) method. Supports negative numbers even though they aren't used in the current protocol.

	import struct

	def pack_varint(val):
	total = b''
	if val < 0:
	val = (1<<32)+val
	while val>=0x80:
	bits = val&0x7F
	val >>= 7
	total += struct.pack('B', (0x80\|bits))

nickelpro / yggdrasil.py

Created October 16, 2013 21:51

Yggdrasil Authentication implementation for Minecraft, implements all known Yggdrasil methods and is a lot simpler than some of the other implementations floating around

	import urllib.request as request
	from urllib.error import HTTPError
	import json

	class YggAuth:
	def __init__(self,
	client_token=None,
	access_token=None,
	username=None,
	password=None

nickelpro / randpng.py

Created April 23, 2013 07:24

Generates a reasonably random PNG image, relies on pypng

	import png
	import random

	random.seed()

	pixels = [[random.randint(0, 255) for i in xrange(0, 3*64)] for i in xrange(0, 32)]

	png.from_array(pixels, 'RGB').save('foo.png')

nickelpro / to_hex.cpp

Last active December 15, 2015 01:29

Creates a std::string of hex from data, data being basically any primitive data type. I have no idea under what conditions this will explode, probably many

	#include <iomanip>
	#include <sstream>

	std::string to_hex(const void *data, const unsigned int size) {
	std::stringstream stream;
	stream << std::uppercase << std::hex;
	const unsigned char bytes = static_cast<const unsigned char >(data);
	for (unsigned int i = 0; i<size; ++i) {
	stream << std::setfill('0') << std::setw(2) << static_cast<const int>(bytes[i]) << " ";
	}

nickelpro / Python Enum

Created November 13, 2012 19:18

Do-It-Yourself Enumeration in Python

	class enum(object):
	def __init__(self, *names):
	for number, name in enumerate(names):
	setattr(self, name, number)

	Example:

	Month = enum(
	"January",
	"Febuary",

	}
	*dest = source & 0x7F;
	return ++dest;
